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...
Due to the characteristics of stainless steel and the special requirements for product quality, the stainless steel cold rolling production process has the following characteristics: (1) Stainless steel is a kind of high alloy steel, which has a large resistance to rolling deformation. In order to carry out high-efficiency and high-precision rolling, a rolling mill with high rigidity should be used, and a multi-roll cold rolling mill is generally used. (2) The multi-roll cold rolling mill generally adopts the single-machine reversible rolling method. The head and tail parts wound on the coiler during rolling are not rolled and are cut off to become waste. In order to improve the yield of the product, a section of lead strip should be welded at both ends of the stainless steel strip before rolling, and the lead strip part should not be rolled; in addition, if the quality of the hot-rolled coil is too small, in order to improve the rolling efficiency and yield; The small steel coils are pre-welded into large steel coils; in the continuous annealing and pickling unit, because of the continuous operation, the head and tail connections of the steel strips also need to be welded. (3) Before the...
Stainless steel coloring methods are as follows: ⑴ chemical oxidation coloring method; (2) Electrochemical oxidation coloring method; (3) Ion deposition oxide coloring method; ⑷ high temperature oxidation coloring method; ⑸ gas-phase cracking coloring method. A brief overview of the various methods is as follows: (1) Chemical oxidation coloring method: It is the color of the film formed by chemical oxidation in a specific solution, including dichromate method, mixed sodium salt method, vulcanization method, acid oxidation method and alkaline oxidation method. Generally, “INCO” (INCO) is used more, but if you want to ensure the same color and luster of a batch of products, you must use a reference electrode to control. (2) Electrochemical coloring method: It is the color of the film formed by electrochemical oxidation in a specific solution. (3) Ion deposition oxide coloring method chemical method: the stainless steel workpiece is placed in a vacuum coating machine for vacuum evaporation plating. For example: titanium-plated watch cases and watch straps are generally golden yellow. This method is suitable for high-volume stainless steel machining. Because of the large investment and high cost, small batch products are not cost-effective. ⑷ High temperature oxidation coloring method: In a specific molten salt, the workpiece...
