The headless welding rolling process starts at the exit of the reheating furnace. After the billet is descaled by high-pressure water at the exit of the reheating furnace, the front end of the billet is butted with the tail of the former billet which has entered the roughing mill. The specific procedures are as follows: (1) When the pulse ...

Welding Sequences: the welding sequence should be well described in the welding procedure. Safety: ultimately, safety cannot be overlooked throughout the welding operation. For instance, when fuel gases are used for preheating, etc., ventilation must be provided Weld quality: the quality of the weld must be constantly checked. The final weld ...

The 3D model in the saVRee database represents a vertical grinding bowl mill.Other grinding mill types include the ball tube mill, hammer mill, ball and race mill, and, roll and ring mill.

Welding Procedure for Can-Am Steel Chain. Preheat chain and attachments to 200 deg - 350 deg F before welding. Preheat temperature is effected by many variables, some are thickness of material, geometry of attachment, and chemical composition of steel. Use a dry 7018 electrode. Always observe proper welding techniques.
