Problems solved by technology

The baking method of these two industrial furnaces is to place the casting sand mold in an oven or a mold baking furnace to heat, so that the heat penetrates from the outer wall of the sand mold into the inner layer and gradually dries. Because of this heating method, the outer surface of the casting mold and the sand box do not need to be heated. The parts must be heated at the same time, which wastes heating time and energy consumption. At the same time, this heating method cannot fully dry the cavity of the casting sand mold, each part of the m

Abstract

The present invention relates to casting technology, and is especially one hot blast furnace with high pressure blower to generate continuous airflow and electric heating element to heat so as to form output hot airflow. The present invention also relates to the stoving method of using the hot blast furnace in stoving casting mold, maintaining hot state of casting mold and eliminating humidity. The technological scheme of the hot blast furnace includes using one motor driven high pressure blower to output continuous airflow, pressurizing the airflow through pipeline to heating chamber and heating the airflow with the electric heating element inside the heating chamber, so as to generate 50-350 deg c high temperature and high pressure airflow. Through metal hose, the hot airflow is forced into the casting mold to stove casting mold, maintain hot state of casting mold and eliminate humidity.

Description

Technical field [0001] The invention relates to the foundry industry, especially a hot blast stove which is produced by a high-pressure fan and heated by an electric heating element to form a hot air flow output. [0002] The invention also relates to a baking method for casting mold hot blast furnace for casting mold baking, maintaining mold heat state, dehumidification and drying and baking. Background technique [0003] At present, the traditional foundry industry has always used box-type resistance furnaces or diesel barbecue ovens for casting molds. The box-type resistance furnaces are equipped with electric heating elements on the inner wall of the box, and the heat generated by the electric heating elements is used to bake casting sand molds. . The diesel barbecue oven uses diesel fuel as the heat generated by combustion and then dries the casting sand mold through an oven. The baking method of these two industrial furnaces is to place the casting sand mold in an ov...
