Abstract

The invention discloses a point-face composite type heating spraying head for a heating furnace. The center of a columnar base is provided with an inserting hole; a center pipe is movably inserted andconnected in the inserting hole; the top of the center pipe is connected with a reducing pipe; a nozzle is arranged at the tail end of the reducing pipe; the edge of the top face of the columnar baseis provided with a plurality of notches, and a gas outlet is formed in each notch; the edges of the notches are each provided with an adjusting rotary knob; each adjusting rotary knob is provided with an inserting groove; by rotating the adjusting rotary knobs, the gas displacement of the gas outlets can be adjusted; and a filtering cylinder is arranged on the edge of the columnar base, and is provided with an air inlet. According to the point-face composite type heating spraying head for the heating furnace, a center spraying port is formed in the center of a body, and flames sprayed out ofthe spraying port are columnar, and are used for point heating in small area. A plurality of heating spraying ports are formed in the periphery of the heating spraying head, the gas outflow amount ofthe spraying ports can be freely adjusted, in this way, flexibility is achieved, the heating spraying head can perform both face heating and point heating, and switching and adjusting are both convenient.

Description

technical field [0001] The invention relates to a point-surface composite heating nozzle for a heating furnace. Background technique [0002] In the metallurgical industry, a heating furnace is a device (industrial furnace) that heats materials or workpieces (usually metals) to the temperature of rolling to forging. Heating furnaces are used in petroleum, chemical, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, pharmaceuticals and many other industries. Some heating furnaces use combustible gas to heat, but the heating nozzles are mostly surface heating, and it is difficult to point heat a certain area. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing a point-surface composite heating nozzle for a heating furnace. [0004] Above-mentioned technical problem of the present invention is mainly solved by...
