How is stainless steel composite plate produced?

Stainless steel composite plate combines stainless steel with base materials such as carbon steel to form a composite material that combines corrosion resistance and structural strength. Its production mainly adopts two processes: explosive composite method and rolling composite method. The specific process and characteristics are as follows: 1、 Explosive composite method 1. Principle: Using the high-pressure shock wave generated by explosive explosion, the stainless steel cladding plate collides with the base steel plate at high speed, generating high temperature and pressure at the impact point, enabling metallurgical bonding (atomic diffusion) between the two metal surfaces in a very short period of time. 2. Process:

What is the function of the rolling mill step pad?

The rolling mill step pad is a key component in the rolling mill equipment, mainly used to adjust the gap between the rolling rolls, control the thickness of the rolled piece, and optimize the stability and product quality of the rolling process. Its core role is reflected in the following aspects: 1、 Thickness adjustment and precision control Dynamically adjust the gap between the rolling rolls The step pad is driven by a hydraulic system, which can achieve rapid switching or continuous adjustment between the steps, thereby accurately controlling the gap (i.e. roll gap) between the upper and lower rollers. For example, in the production of hot-rolled strip steel, the adjustment accuracy of step pads

What are the advantages and disadvantages of self-lubricating wear-resistant plates?

Analysis of the advantages and disadvantages of self-lubricating wear-resistant plates 1、 Core advantages Significant self-lubricating performance No need for external lubrication: By embedding solid lubricants (such as graphite, PTFE, molybdenum disulfide, etc.), lubricating particles are automatically released during the friction process, forming a stable lubricating film and reducing direct contact between metals. For example, the friction coefficient of high-strength brass+graphite composite plate can be as low as 0.05-0.1, significantly reducing frictional resistance. Adapt to harsh environments: able to maintain lubrication effect even under high temperature, humidity, corrosive media or vacuum conditions, avoiding the problem of traditional lubricating oil failure. Excellent wear resistance
