Why choose high temperature plasma cutting technology for wear-resistant steel plate
The cutting technology of wear-resistant steel plates has been greatly improved. In the past, cold-rolled cutting was used for cutting wear-resistant steel plates, but this cutting technology is not conducive to maintaining the shape of wear-resistant steel plates to a certain extent. and hardness are affected, because cold-rolled cutting has an impact on the physical properties of wear-resistant steel plates. So now our wear-resistant steel plate factory adopts high temperature plasma cutting technology. This cutting technology has little effect on the physical and chemical properties of the wear-resistant steel plate.
For the cutting of wear-resistant steel plates, it is recommended to use plasma cutting. Plasma cutting is divided into two types: underwater plasma cutting and air plasma cutting. When underwater plasma cutting is used, the plasma gas can generate a high temperature of several thousand degrees, the high manganese steel plate is rapidly melted at the incision, and oxidation is avoided due to the water barrier, and the water cools the steel plate in time to prevent the precipitation of carbides, so that the steel plate can be cut. The surface is smooth and flat, without heat affected zone, and the cutting quality is the best. It is the first choice for cutting high manganese steel. Air plasma cutting can also be used.
Wear-resistant steel plates can also be cut by traditional flame cutting. When flame cutting is used, it is recommended to use a cutting trolley. According to the thickness of the steel plate, different specifications of gun heads are used. The ratio of gas and oxygen is adjusted properly (preferably neutral flame). It is to start cutting after all adjustments are made, so as to prevent the section gap caused by the flameout and arc ignition in the middle, which will affect the cutting quality.

Steel prices have risen by more than a thousand steel companies generally turn losses into profits
Since the first half of last year, steel prices have begun to recover thanks to a series of measures such as supply-side reforms and elimination of backward production capacity. Taking rebar as an example, the average price on March 9 last year was 2475 yuan/ton, and on March 9 this year, it has risen to 3852 yuan/ton, an increase of 35%.

China Steel Association: Steel prices in the domestic market continued to rise slightly in September
According to data from the China Iron and Steel Association, in September, the domestic steel market demand was strong, and steel prices continued to rise. Affected by the rapid release of steel production capacity, pressure on the supply side has risen, and the price increase of steel has narrowed.
