Abstract

The invention relates to a sand riser with a heating block being combined at the top. The sand riser is characterized in that the sand riser comprises a sand riser body (1) which is of a tubular structure; the sand riser body (1) is made of precoated sand; and the heating block (2) is arranged at the top of the sand riser body (1) and comprises a top cover (2.1) and a sharp corner (2.2), wherein the center of the bottom of the top cover (2.1) is downwards provided with the sharp corner (2.2). The sand riser with the heating block being combined at the top has the advantages that the manufacturing efficiency is high, combination is convenient, strength is high, feeding efficiency is high, and the cost is saved.

Description

technical field [0001] The invention relates to a sand riser of a top combined heating block. Background technique [0002] Traditional sand risers (such as oil sand risers, furan risers) have low production efficiency, low strength and easy capping of the risers; while heating risers or thermal insulation risers are expensive and prone to cracking during pouring, causing castings to run out of fire And scrapped. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above deficiencies, and to provide a sand riser for the top combined heating block with high production efficiency, good strength, cost saving and stable feeding efficiency. [0004] The object of the present invention is achieved in this way: [0005] A sand riser with a top combined heating block is characterized in that it comprises a sand riser main body, the sand riser main body is a tubular structure, the material of the sand riser main body is coated sand, and the to...
