Q:What is the difference between hard steel plate and soft steel plate?
The so-called hard steel plate refers to the steel plate after processing has not been annealed, while the soft steel plate is annealed. Some die steels are subjected to pre hardening, and heat treatment is no longer necessary in the manufacture of injection moulds.
Q:What do you pay attention to?
1, the plastic bumper with 150-320# sandpaper, if the upwarping phenomenon in the injured, also with a knife will become warped skin scraping.2, in addition to oil, dust, after the proportion of the mixture of good ash fill the depression, to dry solid, first with 320-400# sandpaper polished, and then use 600-800# sandpaper grinding.3. After drying, place a primer newspaper at about 40mm of the ash.4, after removing oil and dust, with diluted primer (primer and quick drying diluent ratio of 1:1), empty spray again, dry and then spray again. In order to reduce the number of spraying and grinding time, it is necessary to ensure the smooth flow of primer, without flashing between each time. Dry the surface of the paint film, until the primer lose brightness, you can continue spraying, and then go round and round until you reach the thickness of the depression.5, in order to shorten the volatilization time, can use high temperature equipment baking, do not have to remove the newspaper, dry solid with 600-800# sandpaper to throw flat, but must not wear primer layer leakage.
Q:Stainless steel plate and steel welding
Depends on your stainless steel plate number and steel brand, and then choose the corresponding electrode, in general, commonly used should be 304 stainless steel, steel bar should be Q235, so with 307 of the welding rod can be welded
Q:What are the properties of deep drawing properties in sheet steel?
If the performance is different on the plane, the ear will appear. On the thickness of the performance is not good, there will be leakage phenomenon. Generally, deep drawing properties are indicated by R values.
Q:Is PCM steel better than galvanized steel?
In order to obtain the bending and curing enough; and can obtain good washing resistance, pollution resistance and high hardness. The pencil on the back with modified epoxy paint at the back, one can obtain good corrosion resistance, also can obtain excellent adhesion foaming.PCM color steel plate can not only meet the household appliances use environment and the requirements of the service life, but also has good processability, can meet the high speed and precision machining equipment requirements, can be used for bulk refrigerator door, side plate, back plate, box washing machine, water heater
Q:What is Larson steel sheet pile?"
The advantages of Larson steel sheet piles1. high quality (high strength, light, good water resistance);2., simple construction, shorten the period of time, good durability, life of more than 50 years;3. construction cost is cheap, interchangeability is good, can be reused 58 times;4., the construction has remarkable environmental protection effect, greatly reduces the amount of soil sampling and the use of concrete, and effectively protects the land resources;5., the timeliness of disaster relief is stronger, such as flood control, landslides, subsidence, quicksand and so on;6. Deal with and solve a series of problems in the process of excavation;7, for the construction task, it can reduce the space requirements;8, the use of steel sheet pile provides the necessary safety, and timeliness;9, the use of steel piles can be free from weather conditions;10, the use of steel sheet pile material can simplify the complexity of inspection materials and system materials;
Q:What is the difference between Q235A steel and Q235B steel?
Secondly, in the tensile and impact experiments, the material is Q235A steel, no impact test, the material is Q235B steel to do the normal temperature impact test, V notch. Relatively speaking, the mechanical properties of materials Q235B steel is much better than the material of Q235A steel.
Q:What's the good way to connect two Q235 steel bolts? Why?
The two scheme should be avoided by 1 reasons, is not easy to locate; 2, the mechanical strength is lower than that of Q235 steel plate bolt, bolt if 8.8 or 10.9 has no significance; 3, time is in low efficiency and tap plate fees, high production cost. Only when the space of the tightening nut is not enough can the connection mode of the steel plate upside screw thread be adopted.
Q:Is the cold rolled steel plate good or the stainless steel plate?
Although it is impossible to provide specific parameters to prove, in fact, most stainless steel plates are used in oven making. Corrosion resistant, easy to clean, safe and sanitary.
Q:What welding rod should be used for welding of cast iron and Q235B steel plate?
Such as outdoor and field construction, should be relatively closed work environment, do a good job of wind work, reduce air flow. Two. Use acetylene torch to preheat the welding and its surrounding parts, and then weld them to a temperature. Three, welding side edge knocking release and eliminate stress. Four, slow cooling is correct, after welding torch with air flow slow heating, avoid welding temperature drop.
