When the macro test method is used to inspect the internal defects(white fused alumina make company), it shall be carried out according to the special documents agreed by the manufacturer and the user. If the demander finds harmful defects in castings after acceptance and considers it necessary to return the castings(white aluminum oxide lapping compound), it shall inform the foundry (workshop) within 30 days after the defects are found and solve them through negotiation(only suitable for mechanical property inspection).

(cheap corundum sand wholesale suppliers philippines)During the production period, the appearance quality (surface roughness(aluminum oxide grit), surface defects, dimensional tolerance, etc.) of castings and the internal quality (chemical composition, physical properties, metallographic structure, internal defects, etc.) of castings are comprehensively inspected(aluminium oxide polishing compound). The demander raises objection to the pin material, and the material sample shall be kept for 30 days from the date of sending the test report.

When the capacity of medium steel furnace is not more than 500kg(brown fused alumina for abrasive), under the conditions of stable smelting process and small fluctuation of chemical composition, in order to ensure the quality of products, the castings of the same brand of cake steel produced by the same steelmaking furnace in one shift can be treated as castings with the same melting furnace number(white fused alumina abrasives). The poetry manufacturer can put forward the request for recheck in this room.

When the capacity of heat treatment furnace is small(white aluminium oxide grit suppliers), under the condition of fixed heat treatment process and stable heat treatment quality, the same type of heat treatment furnace is used to separate heat treated parts. The first batch of castings which have been shut down for more than half a year should also be inspected(brown fused alumina powder).
