Temperer

In the event of an accident or system instability, when the pressure of the sludge gas in the pipe decreases, the fire at the point of combustion will spread through the pipe toward the gas source, called a backfire. The device to prevent and block this backfire is called a backfire preventer. It is installed in the acetylene pressure gauge after taking over the line, the gas welding and gas cutting process to prevent the role of backfire. Avoid flame into the gas cylinder, the explosion.

Sector segment

The single continuous casting machine that constitutes the continuous casting line in continuous casting production is generally called sector section, which is generally divided into arc section (or bending section), straightening section, horizontal section and so on. According to the different casting billets can be divided into slab sector, square billet sector, round billet sector. The common production is slab sector section and square billet sector section.

Overview of dust removal guns

Coal field spray water mist dust removal system as an example to outline the composition and performance of the dust removal gun, coal field spray water mist dust removal is mainly through the sprinkler gun high-pressure sprinkling water to play the role of coal field dust suppression, coal field spray dust reduction management. Coal field water mist dust removal is divided into coal field spraying, transfer station dust removal and car unloading coal ditch dust removal.

Crystallizer vibration device

A crystallizer vibration device in a continuous steel casting production process, which consists of a fixed frame, a vibration arm, a vibration frame, a spring steel plate guiding device and a driving device. The vibrating frame is controlled by the spring steel plate guiding device and the vibrating arm, forming a four-link mechanism to ensure that the crystallizer generates arc-like vibration, which causes the crystallizer to reciprocate up and down to prevent the crystallizer from sticking to the billet and to move the billet down along the inner cavity of the crystallizer.

Dust removal gun spray characteristics and uses

The dust removal gun is a high efficiency two-fluid dual-phase nozzle, which has good effect on removing fine dust in flue gas. The gas pressure of the nozzle can be set a constant value, and only the flow rate of the liquid is changed, and the adjustment ratio can be up to 1:10; the particle diameter of the spray is about 100 microns, and the fine dust in the flue gas is separated from the flue gas after bonding, so as to achieve the purpose of dust removal. Due to the large through-hole of the nozzle, which reduces clogging, pool water and external drainage can be used. The nozzle is mainly used for flue gas cooling and dust removal in steel, cement, environmental protection, power plants, chemical and other industries.

Spray properties and applications

The main body of the nozzle is made of rolled copper, thus it has good sealing and wear resistance, and the nozzle can be replaced when it is worn out in use. Its spray shape is bimodal conical, with large coverage, uniform atomization and stable performance, and the nozzle is mainly suitable for secondary cooling of special steel round billet and square billet continuous casting.

Standard solid conical nozzle (vortex nozzle)

Standard solid conical nozzle is equipped with a special design of the internal spoiler blade to make the pressurized liquid produce high-speed rotation and atomization, when the liquid leaves the nozzle mouth, the centrifugal force forces the liquid along the tangential direction of the nozzle high-speed flung out to form a solid conical spray width. Standard solid conical nozzle, with a variety of spray angle design, the size of the spray angle depends on the liquid flow rate and the nozzle structure, the spray angle of our products range from 15 ℃ -12015 ℃.

Standard fan nozzle (pressure type nozzle)

Standard fan nozzle is the most common type of fan nozzle, the liquid into the direction and the direction of the nozzle in the same axis, when the pressurized liquid into the nozzle will produce a pressure chamber, the pressure chamber range from the nozzle mouth to extend inward, spray flow and spray angle are determined by the size of the nozzle mouth and processing angle.

Atomizing nozzle characteristics and applications

This series of nozzles has a novel structure, the connection and installation form is ferrule receiver type, the installation alignment is very convenient, in the process of using the nozzle wear, can be replaced, its spray shape is flat band, with uniform atomization, wide range of water adjustment, not easy to clog, etc.; mainly used for slab continuous casting wide surface of the second cooling and the required atomization of the place of humidification.
