Abstract
The invention relates to a protective atmosphere fast cooling sintering furnace, which is provided by improving a common box type resistance furnace. A stainless steel material is welded to form a sealing cavity; the cavity adopts a rectangular structure; one end of the cavity is positioned in the box type resistance furnace while the other end extends outside the resistance furnace; and a detachable furnace door is arranged at the top of the extending end. The extending end is surrounded by circulating cooling water; and a thermal insulation fireproof layer is arranged between the circulating cooling water and the resistance furnace for protecting. A protective atmosphere can be fed in the stainless steel sealing cavity; an air inlet is formed in the middle of the cavity; and an air outlet is formed in the furnace door at the top. The protective atmosphere fast cooling sintering furnace can be applied to the production of sintering products under the protective atmosphere and cooling the products under the protective atmosphere. The protective atmosphere fast cooling sintering furnace has the beneficial effects of guaranteeing excellent sintering quality of the products under the protective atmosphere, greatly shortening product cooling time, being simple in structure, convenient in use and operation and low in manufacture cost and reducing the production cost.

Background technology
In the production process of diamond metal grinding tool, heat-agglomerating equipment must be used.Diamond metal grinding tool needs to be sintered to about 800 DEG C because of itself characteristic, and normal diamond is heated to 700 DEG C under aerobic environment namely starts to occur carbonization, and metal powder also needs to do anti-oxidation process.Therefore will relate to one and can pass into protective atmosphere, there is the agglomerating plant of airtight cavity.Product sintering terminates simultaneously, needs to reach the effect that can cool fast under protective atmosphere, to enhance productivity, economizes on resources.
Summary of the invention
In order to overcome, product sintering under protective atmosphere terminates to cool slowly, waste material, energy consumption are many and inefficient deficiency; the invention provides the cold sintering furnace of a kind of protective atmosphere speed; this sintering furnace can ensure that product sinters under protective atmosphere in use; reach the effect having sintered rear quick cooling, save material, the energy simultaneously and raise the efficiency.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
The cold sintering furnace of protective atmosphere speed; comprise chamber type electric resistance furnace, stainless steel cavity, thermal insulation layer and circulating cooling water tank; stainless steel cavity airtight end puts in chamber type electric resistance furnace; mid portion is wrapped up by thermal insulation layer; there is circulating cooling water tank openend, and the dismantled and assembled stainless steel fire door of stainless steel cavity hatch is closed.
Technical scheme as a further improvement on the present invention, the dismantled and assembled stainless steel fire door of described stainless steel cavity, with being no less than the openend that 8 are bolted to stainless steel cavity, has the rubber washer as sealing between stainless steel fire door and stainless steel cavity.
Technical scheme as a further improvement on the present invention, in described stainless steel cavity, protective atmosphere air inlet upper end in the middle part of stainless steel cavity, communicates with inner chamber, and gas outlet is in stainless steel fire door bottom.
Technical scheme as a further improvement on the present invention, described recirculated cooling water case and bag are rolled in stainless steel cavity hatch end, and recirculated cooling water, from the water inlet of water tank lower water inlet, is discharged from water tank upper delivery port.
As the technical scheme further improved of the present invention, described product, after the heat-agglomerating of chamber type electric resistance furnace end terminates, moves to circulating cooling water tank end place, realizes the rapid cooling of product under protective atmosphere.
In sum, the invention has the beneficial effects as follows: ensure that product sintering character under protective atmosphere is excellent, terminate rear realization and cool fast, economize on resources and enhance productivity.
