The cold-rolled steel plate is very bright, flat, good in appearance and standard in thickness. When it is not rusted, it is as bright as stainless steel; the hot-rolled surface is rough, the shape is not cold-rolled, and it is iron-gray when it is not rusted

Stainless steel (Stainless Steel) is the abbreviation of stainless steel and acid-resistant steel. Stainless steel that is resistant to weak corrosive media such as air, steam, and water is called stainless steel, or stainless steel; steel that is resistant to chemical corrosive media (acid, alkali, salt, etc.) is called acid-resistant steel.

Essential difference The anode of the galvanized electrolytic equipment is connected to the processing power supply, and the current is used to move from positive to negative to deposit a layer of zinc on the workpiece.

In fact, in daily life, we often use different types of castings, and in actual use, there are many advantages, and we also find that castings are like alloy steel castings with high hardness, so how should we carry out chemical treatment:

1. Polishing method: Driven by the motor, the brush roller and the workpiece to be rolled move in opposite directions in the plate, and the upper and lower surfaces of the brush are rotated at high speed to remove tin oxide. The iron oxide is brushed off using a washing system with a closed cycle cooling water bath. The method of shot blasting is to use centrifugal force to accelerate and blast the alloy steel castings to remove rust and clean.

2. Shot peening method: It is divided into shot peening and sandblasting. The surface is shot peened, which has strong force and obvious cleaning effect. However, the shot peening of the thin plate workpiece is easy to deform. The alloy steel casting and the steel shot impact the surface metal substrate to deform, and the workpiece is oily, so the workpiece, shot peening and shot peening cannot remove the grease. For the workpiece surface of the existing processing method, the sandblasting cleaning effect is good. It is suitable for sandblasting with high surface cleaning requirements.

In the production process of alloy steel castings, after some chemical treatment, after chemical treatment, in the use process of castings, it has a quite obvious effect. Changes to plants can also improve their quality.

Although hot-rolled steel pipe is also a kind of steel pipe, it still has many irreplaceable advantages compared with ordinary products. For example, it can refine the grains of steel by destroying the casting structure of steel ingots, eliminate microstructure defects, and make steel have good mechanical properties. Specifications also help to meet the different needs of consumers, so that everyone can have a high level of product service.
