In the stainless steel plate process, if the temperature of the steel is not uniform, the material flows more in the area with higher temperature, and less in the part with lower temperature, and the high temperature difference causes cracking. The wedge is a measure of the thickness at an edge compared to the average thickness of the edge of the strip or plate. It is desirable to have some bulge in the steel piece so that rolling can be performed with high stability. Roll springs are a defect in which the thickness of the rolled sheet is greater than required, the rolls have been deflected by the high rolling force, and elastic deformation of the mill occurs. Roll deformation can be reduced if a stiffer roll is used, ie a roll material of high stiffness or spring constant. Maintaining a uniform gap is difficult, the rollers deflect under the load required to deform the steel, the deflection results in the steel being thinner at the edges and thicker in the middle, which can be overcome by using crowned rollers, but crowned rollers compensate for a set of conditions, temperature and Deformation, other methods of compensating for roll deformation include...
Stainless steel products are widely used in our daily production and life. For example, our doors and windows, bridges, tools used, etc. are used, which provides us with a lot of convenience. So what problems should we pay attention to when welding stainless steel to ensure the quality of our products? When welding stainless steel products, it is necessary to pay attention to the need to work in a good working environment; in the process of welding stainless steel products, it is necessary to pay attention not to wear glue gloves for processing, because the temperature is too high during welding, and the glue Gloves are easily melted by high temperature; during the welding process, do not touch the relevant welding tools; when cutting stainless steel, it is strictly forbidden to directly cut the stainless steel material stack, and the stainless steel plate should be moved to the site for cutting; if using Manual arc welding requires an anti-spatter coating with a range of 100mm on both sides of the street to easily clean up spatter; during the processing, it is necessary to strictly control the number of cold wind repairs of the stainless steel pressure vessel. It is also...
Stainless steel processing manufacturers have the same feeling: stainless steel is difficult to process. In fact, the reasons for this are as follows: 1: The machining hardness causes the tool to wear quickly and it is difficult to remove chips. 2: Low thermal conductivity causes plastic deformation of the cutting edge and faster tool wear. 3: The built-up edge is likely to cause small pieces of powder to remain on the cutting edge and cause a bad machined surface. 4: The chemical relationship between the tool and the material to be processed causes work hardening and low thermal conductivity of the material to be processed, which not only easily causes unusual wear, but also causes tool chipping and abnormal cracking. The existing solutions to the above processing problems are as follows: 1.: Use a tool with high thermal conductivity, 2.: Sharp cutting edge line: The chip breaker has a wider margin, which can reduce the cutting pressure, so that the chip removal can be well controlled. 3.: Optimal cutting conditions: Improper machining conditions will reduce tool life. 4.: Choose the appropriate tool: The stainless steel tool should have excellent toughness, and the cutting edge strength and the bonding force of...
