Chapter 81 Start of Electric Furnace

On the other hand, after the high-level members of the alliance received the plan formulated by Xia Lin, and after the internal discussions and revisions of the alliance, the alliance's countermeasures were officially implemented. At the same time, the steel saved and raised by the various chambers of commerce was also continuously transported to the Xinglan Industrial Park. .

Soon enough steel reserves were obtained, and Xia Lin immediately started the construction of the electric arc furnace body in the steelmaking plant that had already been built.

First of all, he needs to cast the steel into the shell of the electric arc furnace. There is a small difficulty in this step, that is, the fluidity of the molten steel is very poor, and the castings are usually very thick and the structure is very simple.

Steel castings with a slightly more complex structure like this can also be cast in this way, but problems such as hollowness and defects are prone to occur.

For this reason, Xia Lin proposed a plan for rotating the mold. First, the mold is fired by the lost wax method, and then a rack is installed on the mold. The power of the waterwheel drives the mold to rotate slowly to increase the fluidity of the molten steel poured into it. .

But after trying, Xia Lin found that it was impossible for the power of the waterwheel to move such a heavy mold and the molten steel inside.

In the end, he could only use the most primitive vibration method, that is, people use a small hammer to continuously beat the outside of the mold filled with molten steel under high temperature, and use the vibration transmitted to the inside to help the molten steel fill the inside of the mold.

This method is very crude, and the effect is worrying, but after the finished product comes out, perhaps the high-temperature rune disk provides enough heat for the molten steel, allowing them to have enough cooling time to slowly fill the entire mold.

In short, the quality of the cast steel shell of the electric arc furnace that has been specially thickened is not bad, and it can be used only by grinding off the excess thickened part of the shell, which finally made Xia Lin heave a sigh of relief.

The next step is to build the furnace body and molten pool with magnesia bricks in the shell, and set up cast iron water cooling pipes in it to prevent the furnace wall from being damaged due to the high temperature of the electric arc furnace. The body of the furnace is complete.

After the working layer of the electric arc furnace cover of the Kyle Potion Store is in place, and the three-layer furnace cover is completed and installed on the furnace body, a pocket-sized 2.4-ton electric arc furnace with a diameter of 1.6m and a height of 5m is completed.

According to Xia Lin's design, this electric arc furnace is enough to hold 5 tons of charge. The question is whether the high-energy arc generated by forty arc spell rune disks can completely melt these charges. If not, the charge can only be reduced for production. Long-term Historically arcs have caused some damage to exposed furnace walls.

In addition to these considerations, there is one thing that this electric arc furnace lacks, and that is the lifting system.

The purpose of this lifting system is to lift the electric arc furnace and dump the slag and molten steel. In Xia Lin's previous life, a hydraulic device was usually installed at the bottom of the electric arc furnace to achieve this, but now he does not have such conditions.

This is easy to solve, just use a cable and a hoist.

Xia Lin came to the nearest desk, took out a pen and paper, and began to draw the drawing of the hoist. In addition, there was also the wire drawing equipment needed to make the steel cable, that is, a set of steel plates with small holes drilled by a drill press and the finished hoist.

With Master Fine's rune disk, this kind of small-scale steel processing is still very easy.

"What is this stuff?"

Seeing that the electric arc furnace had been built, Xia Lin began to draw the blueprints again. Master Faen came to Xia Lin's side, looked at the details of the hoist structure that gradually took shape on the blueprints, and asked while stroking his beard.

"This is a hoist, which can use ropes to pull items. We need this machine to help us lift the electric arc furnace for dumping slag and smelted molten steel!"

Xia Lin replied while drawing the blueprint.

After listening to his explanation, Master Fine nodded thoughtfully. No wonder the bottom of this strange electric arc furnace is curved. It turns out that this method is still needed to extract slag and steel.

After drawing the drawing of the hoist, Xia Lin asked Master Fine to cast several steel plates, and drilled a series of small holes in them with a drill press. The largest is 10mm, and the smallest is only 1mm. This is the simplest drawing and grading mold. .

The 12mm thin steel strips are clamped and connected to the manufactured hoist with clamps, and the all-purpose soybean oil is poured on it as a wire drawing liquid, and steel wires of various diameters can be obtained by passing through the small holes of these steel plates one by one.

After the load is removed, the finished steel wire will undergo cold hardening, and its strength will be improved. Then use the hemp rope soaked in grease as the rope core, let the team members weave these steel wires into a steel wire rope with a diameter of 20mm, and then get the main body of the lifting system .

A total of six hoists are arranged on both sides of the electric arc furnace, three of which require manpower to turn the huge ratchet winch to provide power, and the thick and long steel cables pass through the pulleys hanging from the upper part of the steelworks to connect to the electric arc furnace body. This is the lifting system designed by Xia Lin.

After testing, this lifting system can easily lift one side of the electric arc furnace in an empty state. According to Xia Lin's approximate calculation, even when the material is full, it is enough to turn the three ratchet winches manually. Complete the process of tapping.

After the oven process was completed, Xia Lin transferred a group of employees and workers from the brick factory, cement factory and soda ash factory to start trial production.

These fifty employees and workers were organized into five groups by Xia Lin. One group followed him and was responsible for recording various data about the operation of the electric arc furnace and conveying his instructions to the other groups. There were also three of them who were very familiar with electric arc furnace steelmaking. Dwarf masters who are interested, they are also the seeds of the furnace leader that Xia Lin fancy.

The remaining four groups have two groups responsible for managing the ratchet winch for lifting the electric arc furnace, one group is responsible for standing on the cast iron channel above the electric arc furnace and is responsible for feeding the furnace door, and the other group is responsible for holding the 22mm thick hexagonal steel on the other side. When the electric furnace is powered off, the furnace is quickly pounded.

These two jobs are extremely hard and dangerous jobs. Xia Lin offered them a daily salary of 1 silver Maar plus an additional subsidy of 3 silver Maar a day. In case of danger, there will be 15 Jinlund pensions gold to their relatives.

With such generous treatment, these 20 people put their life and death aside, wearing black goggles and masks with exposed eyes on their heads, heat-insulating clothes and skirts insulated with diatomaceous earth, and tied around their necks. cloth strips, wearing thick gloves on their hands, and after repeated simulation exercises, they are ready to go to their battlefield.

"Stuffing!"

After several times of running-in drills, and letting the employees and workers familiarize themselves with the safety production management regulations of the steelmaking plant, in the steelmaking plant, Xia Lin finally announced that he would start charging the electric arc furnace for smelting. .

First, a large layer of lime was laid on the bottom of the furnace, and then pig iron and wrought iron purchased from the market were added. After the charging was completed, the furnace cover was slowly closed, and the workers in the charging group stepped back.

Xia Lin inserted the magic crystals into the rune disk one by one with the hands of a mage, activated the arc spell rune disk on the furnace cover, and observed carefully, but found no current leakage.

It seems that the insulating layer made by myself is quite reliable, so it is also feasible for workers to inlay and remove the magic crystal to activate the rune disk through the insulating clip.

With the activation of the rune disk, there was a faint sound of electric current coming from the furnace cover, and the temperature around the electric arc furnace gradually began to rise, and soon reached an unbearable level. Xia Lin began to estimate the approximate time.

　Thank you Xixi Shiyao, charge is justice, dim morning light, book friend 160509164720368, C-level executive staff of the Strategic Deception Bureau, and the monthly pass of White Rainbow 233!Thank you for your votes and subscriptions!Thanks for the support!

　　One more thing, brothers, after today I will degenerate into a two-gen beast, because the quality is really not good without saving the manuscript for repeated revisions.

　　For the second update, I only need to code three chapters a day and then modify it. For the third update, I have to code at least four to five chapters a day, and then there is basically no time for revision. There are too many manuscripts and I choose an opportunity to add more, I am really sorry, I am too weak
