Abstract
The utility model relates to a high neck flange formed steel like Chinese character 'chang' used as a tank mouth material in chemical reaction devices, pickling devices, and pressure vessels such as glass-lined steel open and close reaction tanks, glass-lined steel storage tanks, glass-lined steel heat exchangers, etc. Also the utility model can be used for petrochemical industry, medicine, metallurgy, agricultural chemical, colorant, rubber, food, etc., adopts ordinary carbon constructional steel for processing and forming by hot rolling, and the high neck flange formed steel like the Chinese character 'chang' whose manufacturing technology is simple, is composed of a neck, the upper part of the neck edge, the thick part of the neck, and the lower part of the neck. After rolling, a steel user of vertical stripe type can weld according to the size of the tank mouth diameter, and then can mould by a small amount of cutting processing; the mechanical processing can save a great amount of metallic materials, and the usage rate of the steel is high.
Description
A kind of chemical machinery industry that is used for is made chemical reaction, anticorrosion equipments such as enamel open and close type retort, basin, heat exchanger, jar gate material---" factory " font hubbed flange shaped steel of pressure vessel etc.
At present, domestication construction machinery industry is made the jar mouthful employing blank shaped steel of enamel open and close type retort and the required usefulness of anticorrosion equipment and is made through machining, and this jar mouthful of metal cutting amount is big, the waste metal material.The utility model " factory " font hubbed flange shaped steel is through hot rolling machine-shaping with carbon structural steel, technology is simple, after vertical bar shaped steel user after rolling welded according to jar mouth diameter rule circle, promptly plastic through a spot of machining, machining can be saved a large amount of metal materials.
The purpose of the utility model " factory " font hubbed flange shaped steel invention is that the reaction for industries such as petrochemical industry, chemical industry, medicine, metallurgy, agricultural chemicals, dyestuff, rubber, food, the jar mouth of anticorrosion equipment provide a kind of processing technology simple, can save the hot-rolled steel section material of a large amount of metal materials---" factory " font hubbed flange shaped steel.
The summary of the utility model " factory " font hubbed flange shaped steel summary of the invention:
" factory " font hubbed flange shaped steel is to adopt carbon structural steel " factory " font shaped steel through hot rolling machine-shaping.
See shown in the accompanying drawing: 1 is the neck of " factory " font hubbed flange shaped steel in the accompanying drawing, and neck length is 49～85mm, and neck is wide to be 8～20mm, and it is bevel for welding that one 30 °～50 ° chamferings are arranged in the lower end of neck; 2 be neck along top, neck is that 40～80mm neck is circular arc with neck along top and is connected along last minister, arc radius is R=15～20mm, neck and neck are that the jar of retort and anticorrosion equipment is mouthful inner along top, are the machined surfaces that adopts enameling process; 3 be neck along thick portion, thickness is 21～50mm; 4 is that neck is along the bottom, neck is 22～35mm along the length of bottom, and neck is that circular arc is connected along the junction, bottom with neck, arc radius R=5～10mm, neck has one 4 * 60 ° of chamferings along thick with neck along the junction, bottom, be the last lower tank fastening point of attachment of clamp herein.
The utility model " factory " font hubbed flange shaped steel manufacturing process is simple, cheap, and the steel utilization ratio height can be saved a large amount of metal materials.
