What do shipyard firefighters do?

In shipbuilding industry, initiating explosive device is a technology of thermal deformation treatment for specific plates.

Fireworks can be divided into infield and outfield. The external field mainly corrects the hull sections and hull components, and the internal field mainly corrects the curvature and line shape of the hull outer plate. It's basically a water-fire bending plate.

Water-fire bending plate

It refers to a bending method which uses an oxygen-acetylene torch to locally linearly heat the plate along a predetermined heating line, and then cools it with water (or lets it naturally cool), so that the plate produces local plastic deformation, thereby bending the plate into the required curved surface shape. Some countries call it linear heating method. Hydro-thermal bending is the main process method for bending complex curved plates and large internal components of ships in most heavy industries such as shipbuilding and steel structure.

The types of pyrotechnic correction can be divided into:

1, line

2. Dots

3. Long strip

4. horseshoe

Job requirements: 1. According to the linear requirements of samples and boxes, operate the hydraulic press and pyrotechnic faucet, and perform pyrotechnic processing on the cut parts with linear or complex linear outer plates at the head and tail according to the requirements of operating standards, so that the linearity of the parts meets the design and quality requirements. 2, according to the hydraulic press maintenance manual, daily maintenance of equipment, cooperate with maintenance personnel for equipment maintenance, secondary maintenance and repair. Requirements: technical secondary school degree, major in hull and pyrotechnics; Familiar with hull line type and hull lofting, familiar with the operation of pyrotechnic processing equipment, with open flame operation certificate and hook certificate, and more than three years of independent operation experience of pyrotechnics.
