Usage

This equipment is mainly used for the precise components vacuum light annealing, tempering, solid melt effectiveness, vacuum brazing etc of the high-speed steel, molding tool steel, stainless steel, alloy steel,

titanium alloy etc. It has the features of nonoxidation, no carbonization, good the surface quality, and distorts slightly, outstanding comprehensive mechanics performance and no pollution.

Feature

Single chamber, internal heat type, compact furnace body structure.

Installing a convection heat installation, the temperature is evener under low temperature condition of the furnace .

Designing a reasonable heat screen, to guarantee a high thermal efficiency in the chamber.

Structure

The vacuum braze furnace is divided into vertical and the horizontal-type these two kinds. According to the furnace temperature height and the customer technological requirement, use the graphite either the molybdenum or the tungsten to make the heating element and the heat shield. Heating element is separable to arrange. Various areas control warm, programmable PID adjusts independently. The chamber may be whole emigrated, and be advantageous for the maintenance. Provide the gasification installment, may fill the protection gas or the working gas sufficiently to the furnace, the gasification current capacity adjustable. Providing internal recycling cooling system may accelerate the material to cool in the furnace, reducing the action cycle and favoring to improve the product quality and the working efficiency.
