Founded management has universal applications in many fields. In order to ensure that the square management has excellent quality in the actual application process, and to obtain good use effects, when the production and production party management, the guidelines and need to be followed needed to follow There are many notes, such as the material principle of the ingredients.
When the opponent's tube is used for ingredients, we must insist on combining theoretical ingredients and practical experience. Regardless of the test algorithm or diagram method, the theoretical ingredient data cannot be determined as the final ratio; it is necessary The law of changes in elements is based on appropriate adjustment of raw materials.
At the same time, it is necessary to master the chemical composition and reducing laws of various elements of various elements in the furnace metal materials, and the classification and number records of the return of the furnace iron, and propose strict requirements of clear components. The restored elements in the furnace are subtracted at the time of the ingredients, and the elements burned in the furnace are supplemented at the ingredients.
The alloy elements in the square pipe ingredients must be based on the principle of one -time incoming. When the ingredients except 3, the medium limit is taken. less. 03 It can be added when picking slag and breeding.
Since the amount of 0 and 3 in the square tube is mainly derived from the new -ray iron, the amount of 0 and 8 can be controlled by selecting the furnace material within the required range, so the 0.06 of the new iron must be calculated when the ingredients are calculated. You can not consider it because the technical requirements of the casting are different. In addition, all metal materials who have to enter the furnace are required to be measured accurately, so as to produce high -quality square pipes.
