Chapter 172 You Have to Make It All Yourself
Li Yang examined the drawings, his joy beyond words.
This was the first large-scale complete equipment he designed seriously after entering the technical department.
Although there is still a certain gap compared with the fully continuous rolling mills in the 1980s and 1990s, it is already a revolutionary leap for steel mills of this era!
In his mind, he had already drawn up a blueprint for a brand new steel mill.
With rows of new rolling mills and a constant flow of steel products, the entire factory is full of vitality and thriving.
But Li Yang also knew that the design drawings were only the first step in a long journey.
There are still many difficulties to overcome in order to make the design a reality.
The first thing to be affected is the problem of raw materials and processing equipment.
In this era, the steel industry was still small and advanced rolling mill manufacturing materials were scarce.
At the same time, machining and casting processes are also difficult to achieve the accuracy required by the design.
Not to mention the hydraulic, electrical and other supporting parts, which were almost blank at the time.
These are the real dilemmas that Li Yang must face.
After putting away the drawings, Li Yang stood up and stretched his muscles which had become stiff from sitting for so long.
He walked to the window and looked into the distance with a firm and far-reaching gaze.
After a short rest, Li Yang had already outlined a grand blueprint in his mind.
He knew that to turn this blueprint into reality, design drawings alone were far from enough, and there were too many supporting issues that needed to be resolved.
Li Yang sat back at his desk and spread out a new drawing.
He first drew several boxes on paper, representing key components such as the hydraulic system, electrical system, and transmission system.
Then he began to fill in the details one by one.
First up is the hydraulic system.
In this era, hydraulic technology was still very immature and suitable hydraulic components were simply not available on the market.
Not to mention that these things are very technologically advanced in this era, and they are blocked and there is no channel at all.
Li Yang frowned, he knew what this meant - from the hydraulic pump, hydraulic valve, to the hydraulic cylinder, everything had to be designed and manufactured from scratch.
Pick up the pencil and sketch out the structure of the hydraulic pump on the drawing.
To improve efficiency, he chose a vane hydraulic pump.
But the problem is that the vane pump has very high requirements for processing accuracy, and the gap between the shaft and the vane must be controlled at the micron level.
This was nothing short of a fantasy for the machine tools of the time.
Li Yang thought for a moment and wrote the words "Small World Processing" in the corner of the drawing.
That's right, he decided to use the small world to process these precision parts with his mind.
Next comes the hydraulic valve.
Compared with vane pumps, hydraulic valves are slightly easier to process, but come in a variety of models and specifications.
Li Yang estimated that it would be difficult to completely control himself in a short period of time.
So he wrote the words "partially self-made" on the drawing.
As for the hydraulic cylinder, although the structure is simple, the processing quality of the inner surface of the cylinder is crucial.
If the surface is rough, it is easy to cause oil leakage.
Li Yang pondered for a while and decided to use the casting + honing process to improve the surface smoothness as much as possible.
After the design of the hydraulic system was completed, Li Yang turned his attention to the electrical system.
Compared with hydraulic components, there are more types of electrical components.
Motors, transformers, switches, relays... It took Li Yang a lot of time just to make a list.
The trickiest part is the electric motor.
The new rolling mill required high-power, variable-frequency speed-regulating AC motors, which was a cutting-edge technology at the time.
I had to turn my attention to the small world again.
He plans to first use the small world to process the silicon steel sheets for the stator and rotor, and then wind the coils himself and assemble them into shape.
In addition to the motor, the transformer is also a big problem.
Large transformers not only consume a large amount of copper and silicon steel, but also have a very complicated winding process.
In this way, Li Yang analyzed and deduced one by one on the drawings, looking for a breakthrough in the technical bottleneck.
Gradually, drawings filled the entire desk, each one densely covered with notes and comments.
From material selection to process design, from processing plan to assembly process, Li Yang planned every detail. Sometimes he closed his eyes in contemplation, sometimes he wrote furiously, completely immersed in the world of design.
Outside the window, the night deepened. Li Yang finally finished the last drawing and breathed a sigh of relief.
He stood up and stretched his stiff neck, but his eyes became brighter.
Looking around, his eyes swept across the pile of drawings on the table, and a confident smile appeared on the corner of his mouth. He had already thought of the next plan.
First of all, we need to gather the backbone forces of the factory and set up a special technical reform team.
Give them the drawings and let them work separately.
Some people are responsible for the manufacture of simple parts, while others are responsible for contacting outsourcing channels.
For those key components with high technical difficulty and strict precision requirements, Li Yang decided to do it himself.
The plan is to use the small world and adopt the strategy of "breaking them one by one" to overcome those seemingly impossible problems one by one.
Of course, drawings and ideas alone are not enough, a large amount of raw materials are also needed as a guarantee.
Li Yang took stock of the things he had on hand and made a detailed purchasing plan.
Needless to say, steel, copper, silicon steel, insulating materials, etc. must also be prepared in advance.
Li Yang's gaze fell on the lower right corner of the drawing, where the words "Red Star Steel Rolling Mill" were marked.
The rolling mill is only the first step. Fundamentally improving the machining level is the key to achieving independent control. He secretly vowed in his heart that he must put the new machine tool workshop into use as soon as possible.
Thinking of this, Li Yang felt that the responsibility on his shoulders was even heavier.
Li Yang took a deep breath, his eyes firm and hopeful, and gently sorted out the drawings.
Outside, the moon is bright and the stars are brilliant.
