Global crude steel production fell 6.5% year-on-year in July

On August 23, the World Steel Association (WSA) released global crude steel production data for July 2022. In July, the crude steel output of the 64 countries and regions included in the statistics of the World Steel Association was 149.3 million tons, a year-on-year decrease of 6.5%. Steel prices have fluctuated frequently recently. In July, African crude steel output was 1.2 million tons, down 5.4% year-on-year; Asia and Oceania crude steel output was 110.1 millio

European Steel Association slightly raises 2022 steel demand forecast

Eurofer has slightly raised its apparent steel demand forecast for 2022, but still expects consumption to fall year-on-year and expects the market to recover in 2023. Steel consumption in the EU will continue to decline in the second half of 2022 as supply chain disruptions, rising energy prices, inflation and the Russian-Ukrainian conflict continue to affect the European steel industry. The European Steel Association expects apparent EU steel consumption to fall by

Features of Pressure Vessel Plates

Pressure vessel steel plates refer to carbon steel and low alloy steel plates used to manufacture pressure vessel shells. It includes carbon steel, carbon-manganese steel, micro-alloyed steel, low-alloyed high-strength steel, and low-temperature steel. The working temperature is generally -20°C to 500°C, and individual can reach 560°C. Among them, it mainly refers to 16MnR steel (16 manganese capacity low alloy steel, a type of steel), which is used to manufactur

Types and uses of hot rolled steel sheets

The hot-rolled steel plate is made of continuous casting slab or blooming slab as raw material, which is heated in a walking furnace, descaled by high-pressure water, and then enters the rough rolling mill. Rolling, after the final rolling, it goes through laminar cooling (computer-controlled cooling rate) and coiling by a coiler to become a straight coil. The head and tail of the straight hair curler are often tongue-shaped and fish-tail-shaped, with poor thickness and width accuracy, and the edges often have defects such as wave shape

Features of Silicon Steel

Silicon steel refers to silicon alloy steel with silicon content of 1.0 to 4.5% and carbon content of less than 0.08%, called silicon steel. It has the characteristics of high permeability, low coercivity, and large resistivity, so hysteresis loss and eddy current loss are small. Mainly used as magnetic materials in motors, transformers, electrical appliances and electrical instruments. In order to meet the needs of punching and shearing when manufacturing electrical appliances, a certain degree of plasticity is also required. In order

Process flow of galvanized steel sheet

The galvanizing production line is a complete set of equipment for hot-dipping a layer of zinc alloy coating on both sides of the steel coil. It is composed of finishing machine, tension leveling machine, oiling machine, shearing machine, winding machine and other equipment. The main process flow of galvanized sheet Coiling → double unwinding → cutting head and tail cutting → weldi

Production process of seamless steel pipe

The production method of seamless steel pipe is roughly divided into the cross-rolling method (Mennesmann method) and the extrusion method. The cross-rolling method (Mennesmann method) is to first perforate the tube blank with a cross-roller, and then extend it with a rolling mill. This method has a fast production speed, but requires higher machinability of the tube blank, and is mainly suitable for the production of carbon steel and low-alloy steel tubes. The extr

Straight seam welded pipe standard

1. The specification of seam submerged arc welded thick-walled welded pipe for general low-pressure fluid transportation (SY5037-2000) is made of hot-rolled steel coil as the tube blank, which is often spirally formed at high temperature, and is made by double-sided automatic submerged arc welding or single-sided welding. It is used for submerged arc welded steel pipes for general low pressure fluid transportation such as water, gas, air and steam. 2. The specificat

Production steps of spiral steel pipe

Do you know the production steps of spiral steel pipe? Below, I will introduce it to you in detail. (1) Various inspections of raw materials are carried out. Raw materials generally refer to strip coils, welding wires, fluxes, etc. Strict physical and chemical inspections should be carried out before investing to ensure quality. (2) The head and tail of the strip are butted by si

Characteristics of Alloy Steel Plate or Sheet

With the development of science, technology and industry, higher requirements are put forward for materials, such as higher strength, resistance to high temperature, high pressure, low temperature, corrosion resistance, wear and other special physical and chemical properties. To meet the requirements, alloy steel plates appeared. The steel plate is flat, rectangular and can be directly rolled or cut from wide steel strips.
