Abstract

The invention discloses a high alloy steel decarburization-proof annealing box and a process. The annealing box consists of a box body and sealed covers. The annealing box is characterized in that: the box body has a cylindrical long tube shape, and the front port and the rear port of the box body are provided with a rear sealed cover and a front sealed cover; the concave surface inside diameters of the rear sealed cover and the front sealed cover are matched with the outside diameter of the box body, and the rear sealed cover and the front sealed cover are fixed through corresponding fixing rings on the covers and the box body; and three vertical reinforcing ribs are uniformly distributed on the box body. The annealing box used with a decarburization-proof agent can ensure the quality of annealing and decarburization; and the annealing box is convenient to model and manufacture, and has wide use and simple operation.

Description

technical field [0001] The invention relates to an annealing box and a process, in particular to a high-alloy steel anti-decarburization annealing box and a process for high-carbon high-alloy steel. Background technique [0002] The problem of excessive annealing and decarburization of high-carbon steel, especially high-carbon and high-alloy steel, is a major problem that has plagued the heat treatment process of such steel for a long time. At present, the advanced method is to use a controlled atmosphere furnace for protection, or to use a vacuum furnace for annealing. But these two furnaces are expensive, the furnace production capacity is limited, and the annealing production cost is relatively high. At present, in mass annealing production, trolley-type furnaces and car-type masonry furnaces are usually used. Then, how to ensure the annealing quality of these conventional annealing furnaces, especially the problem of excessive annealing and decarburization of high-carb...
