316L stainless steel tube changed the hard state of the original cold rolled tube
Gas protection bright annealing furnace: There are two parts, bright annealing furnace furnace and ammonia decomposition into a set of devices.
Bright Annealing Furnace Body: The main structure consists of a circular section muffle tank. The heating method is adopted on both sides and the bottom part of the high temperature heating wire. The ammonia decomposition gas is used as the protective gas and the circulating cooling gas. Compact structure, safe operation, reliable control and easy maintenance, uniform furnace temperature (up to 1150°C), low source loss, full use of protective gas, fast cooling speed, guaranteed to prevent reprecipitation precipitation of chromium carbide, make all Chromium carbide completely dissolves into the austenite matrix, which changes the hard and metal structure of the tube after cold rolling and achieves the purpose of solution treatment. glenflange
