Abstract

The invention discloses a method for manufacturing an acid resistant fluid container, and belongs to the technical field of machinery manufacturing. The processing method comprises the following steps: (1) preparing the fluid container material; (2) casting the fluid container; (3) preheating the fluid container; (4) conducting fine finishing on the fluid container; (5) heating the fluid container after fine finishing in an induction heating furnace to 820-890 DEG C, and insulating for 3 h, and conducting oil quenching; and (6) heating the fluid container treated in the step (5) to 500-550 DEG C, insulating for a while, and cooling in the furnace to 200 DEG C, and discharging and conducting air cooling. The invention solves the problem that fluid container can be easily corroded by the containing acid fertilizer solution in the existing mechanization fertilization process, and has the advantages of simple method, low cost and easy processing.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and more specifically relates to a method for processing and heat-treating an acid-resistant liquid tank. Background technique [0002] In agricultural mechanized fertilization, some acidic fertilizers, such as ammonium sulfate and superphosphate, are commonly used, but in order to better allow plants to absorb, the fertilizer is generally made into a solution. In the process of mechanized fertilization, the liquid tank containing the liquid not only needs to bear the gravity of the liquid and the impact of the liquid during the transportation operation, but also needs to withstand the corrosion of the acidic liquid. Therefore, for the design of the liquid tank, it is necessary to consider its acid resistance. performance. Contents of the invention [0003] In view of the problem that the liquid tank is easily corroded by the acidic fertilizer solution contained in the existin...
