Q3110抛丸机所用衬板和护板按说明书规定材料应为特种铸铁。由于这种铸铁需要特殊配料和熔炼,一般均由定点厂生产,往往产生供货脱节问题而影响生产,成本也高,而且铸铁衬板和护板脆性大,变形后无法校直,若用螺栓压紧时易从螺孔处断裂。我们曾采用外购的左侧衬板,左托衬板和厚度为5～6毫米的A3钢制的右侧衬板、右托衬板在机器上作对比试验。发现了A3钢制的衬(托)板的使用寿命并不比用特种铸铁制的衬(托)板低,而且成本只有特种铸铁的1/3,同时来源方便。现在我厂Q3110抛丸机上的左、右侧衬板,左、右托衬板,左、右角衬板,底衬板,左、右衬板,圆形板和长护板等均已改用A3钢板,这一改进
Q3110 shot blasting machine used liner and guard according to the instructions stipulated that the material should be special cast iron. Because this kind of cast iron needs special ingredients and smelting, it is generally produced by designated factories. It often produces problems of supply and supply disconnecting and affects the production. The cost is also high, and the cast iron liner and the guard plate are brittle and can not be straightened after being deformed. When pressed easily from the screw hole rupture. We have used outsourced left-side liners, left-line liners, and right-hand A3 liners with thicknesses of 5 to 6 mm. The right-hand liners were compared on the machine. Found that the A3 steel liner (care) plate life is not less than the special cast iron liner (care) plate, and the cost is only 1/3 of special cast iron, at the same time convenient source. Now I plant Q3110 shot blasting machine on the left and right liner, left and right care liner, left and right corner liner, liner, left and right liner, circular plate and long shield have been used instead A3 steel, this improvement
