Mould thermal treatment inspection | |||||||||
Exterior inspection | 1:no crack, no burn marks, no corrosion trail after thermal treatment. 2:left two times spare parts of grinding, depth of surface oxide layer can not reach 1/3 of layer. | ||||||||
Hardness inspection | 1:effective working spare parts should be inspection. 2:it should be according to the drawing 3:when inspection, all should be according to the test of hardness. 4:inspection should not be made on high quality spare part’ surface | ||||||||
Modification inspection | 1:sizes from thermal treatment should be in the scope of drawing. 2:if have two times allowance of grinding, modification should be less than 1/3-1/2 of grinding. 3:oxide layer of surface should not more than 1/3 of machining surplus. 4:roughness of mould datum should be less than 0.02mm. | ||||||||
metallurgy inspection | Mainly inspect metallurgy tissue and penetration depth from thermal treatment. | ||||||||
