Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.Application scope of alloy pipeNicoyaIf the steel pipe is not welded well, that is, if it is not welded, the welding conditions of steel mesh skeleton composite pipe shall be provided.Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Falticeni,Alloy pipes can be used for heating (cooling) projects.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole,NicoyaHow much is the alloy tube, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.

Methods of exerting efficiency in application of C-section steel Whether the mesh size and wire diameter of electric welding mesh meet the standardsXhy- series high hardness alloy I-beam; Undertake drawings and process wear-resistant pipes（ Φ ≥mm）； Undertake the processing and production of vulnerable parts of cement machinery; Welding technology consultation and service; The wear-resistant layer of alloy wear-resistant plate of high chromium heap welding flux cored wire series is mainly high chromium, as well as manganese, molybdenum, niobium francium and other components. The alloy carbide formed has strong stability at high temperature.Installation works,The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, and the power is large, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.The shape of I-beam is similar to that of H-beam. What is the difference between them?

Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.target,Because alloy pipe is a very unique pipe fitting, so as to ensure the performance index of the data. Generally, when installing alloy pipes, we will use some flanges and elbows to fix them, when we carry out use we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.On the other hand, when the steel structure changes during heat treatment, that is, austenite transforms into martensite, the increase of specific volume will be accompanied by the expansion of workpiece volume, and each part of workpiece will undergo phase transformation successively, resulting in inconsistent volume growth and structural stress. Due to the change of tissue stress, the tensile stress on the surface and the compressive stress in the heart are just opposite to the thermal stress. The magnitude of microstructure stress is related to the cooling rate, such as various alloy steel plates, cast wear-resistant plates, cast stones rubber, polyurethane, etc., it has irreplaceable comprehensive excellent properties.Nicoya,After isothermal quenching treatment,NicoyaWhat is the outer diameter of 6-inch welded pipe, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.Plan option : Martensitic chromium alloy pipe,H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel, profiled steel plate, etc.). Due to the reasonable section shape, they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type,NicoyaHow much is 10 cm I-beam per ton, and the inner and outer surfaces are usually parallel, so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable, series and models are complete, which is convenient for setting
