Abstract

The invention relates to the technical field of casting manufacturing cooling, specifically a quantitatively controlled atomization cooling device, which solves the technical problems in the background technology, and includes a liquid delivery pipeline, a gas delivery pipeline, a cooling liquid quantitative control unit, and a gas quantitative control unit , Ladder-shaped Venturi tube, conical Venturi tube, spray chamber, double sets of joint hose, nozzle and airtight box. The invention utilizes the cooling liquid quantitative control unit and the gas quantitative control unit to carry out quantitative control on the cooling liquid and compressed gas; the cooling liquid is automatically sucked into the pipeline through the negative pressure effect generated by the stepped Venturi tube and the conical Venturi tube, and at the same time, it can Increase the airflow disturbance to make the atomized flow more uniform and sufficient; the turbulent airflow generated by the double set of joint hoses can prevent the formation of liquid accumulation during the transmission of the atomized flow; the double sets of joint hoses can be flexibly bent, suitable for different environments, Cooling of complex workpieces; the fogging effect is good, which ensures the quality of casting slabs.

Description

technical field [0001] The invention belongs to the technical field of casting manufacturing cooling, in particular to a quantitatively controlled atomizing cooling device. Background technique [0002] In the continuous casting production process of castings, due to the fast production cycle, the temperature of the slab drawn from the mold of the continuous casting machine is high, and shrinkage cavities and cracks are prone to occur, which affects product quality and life. In order to ensure the quality of slab production, it is necessary to use the atomization cooling process in the secondary cooling zone of continuous casting for forced cooling. However, the traditional atomizing cooler has problems such as spray volume, uneven atomization, and liquid accumulation during the transmission of the atomized flow, which leads to larger sprayed water droplets and poor fogging effect, resulting in a The inconsistency of cooling intensity leads to the formation of cracks. At th...
