Abstract:
A glass lined reaction tank for chemical and pharmaceutical industries and a manufacturing method thereof. One-step molding technical standards for manufacturing iron blanks of the glass lined reaction tanks are deeply developed, an overall structure of a flanged big flange of a tank body and a tank cover matching with the tank body are innovated, and nominal pressure of the big flange and the sealing performance of a tank mouth are perfectly improved. By using a new structurally-combined precise controlled internal heating type electric furnace and an intelligent temperature program control/adjustment/recording instrument, heating temperature of an overall glass lining layer on an inner wall of the tank body is more accurately controlled to be the same, and a synchronous, integral and controlled sintering core technique is realized.

Claim (Index 19):
The precise controlled internal heating type electric furnace according to  claim 17 , characterized in that the ring body planar electric furnace ( 10 ) of the precise controlled internal heating type electric furnace consists of a ring planar electric furnace ( 10 a ) and a straight ring body electric furnace ( 10 b ), the straight ring body electric furnace ( 10 b ) correspondingly auxiliary heat the outside of the first big flange ( 3 a 4 ) of the inner cylinder body ( 3 ) and the overall outer side structure component of the end portion of the first big flange of the tank body ( 2 ) to more accurately and effectively control the heating temperature of the overall glass lining layer be the same, thoroughly eliminate various potential hazards and defects on the inside wall glass lining layers to the utmost extent, which includes realize the highest quality index of zero pinhole, and guarantee that the big flange surface is absolutely not deformed after repetitive high-temperature sintering, the nominal pressure of the big flange surface and the overall sealing performance of the tank mouth are perfectly improved, and after the glass lining layers on the inner walls are sintered and inspected as qualified, the glass lined reaction tank which comprehensively satisfies requirements on Class III pressure vessels can be obtained.
