High precision titanium alloy resistance heating furnace

Abstract

The invention discloses a high precision titanium alloy resistance heating furnace. The high precision titanium alloy resistance heating furnace comprises a furnace body and a heating controller and is characterized in that the furnace body consists of six side plates; the cavity in the middle of the furnace body forms a hearth; a movable furnace door is arranged on at least one side plate; electric heaters are arranged on the inner sides of the six side plates of the furnace body and used for heating the hearth; a plurality of circulating fans are arranged at the top of the hearth; a furnace shell is arranged on the outer sides of the six side plates; the furnace shell is welded by profile steel and plates; and the furnace body can meet the requirements on heating and heat treatment at different temperature sections of 350 to 1,150 DEG C. The high precision titanium alloy resistance heating furnace has high heating speed in the heating process and high furnace temperature uniformity, furnace temperature stability and the like, meets the requirement of the heat treatment process and meets the heating or heat treatment requirement of the titanium alloy from low temperature to medium temperature and high temperature. One furnace can meet the requirements on heat treatment at different temperature sections of 350 to 1,150 DEG C.

Description
