Summary: Magnesium oxide MgO-C is a basic high-melting (melting point 2800 deg.] C) and high melting point of the slag carbon material difficult to invasion as a raw material of non-oxide to add various additives. Bonded with the binding agent does not burn carbonaceous carbon refractory composites. The main site for the MgO-C converter, AC electric arc…

Structure diagram of system is as shown in figure. The system includes electrical master control cabinet, site operation box, LMM1000 special illuminator, camera module, terminal splitter and medium splitter. The system is capable in video image capture, video image information processing, target tracking, counting, steel-splitting, etc.
Parking is smooth, not happen before rebar phenomenon (or before impact and < 50 mm); Stable starting, not after take phenomenon after (or take < 50 mm); Round steel in the region of the count before and after rolling Production site ensure cameras camera is clear, counting area is not obscured. Gather groove direction transfer…
The specific steps are as follows: Camera module obtains bar digital image from bar end, and cuts out effective part; the bar center will be obtained through machine visual technology processing in graphics processor. Self-learning program dynamically tracks center of bar and counts.
All systems consist of master control cabinet, composite special lights, special camera platform and machine separation device. After finishing project, the system has the following functions: video signal capture, video image information processing, target tracking and counting, determination of steel-splitting position, mechanical steel-splitting, etc Automatic steel bar counting system can achieve automatic counting online. The…
Bonding, oxidation color and performance mismatch are the three major problems in the annealing process of cold rolled sheet, especially the two defects of bonding and oxidation color are more prominent. First, the cause of the bond The tension is too large. Tension is one of the main causes of steel coil bonding. The tension…
High carbon concentration Causes and hazards If the carburization is heated sharply, the temperature is too high, or a new carburizing agent is used in the case of solid carburizing, or a strong infiltration agent is too much, the carburization concentration is too high. As the carbon concentration is too high, massive coarse carbides or…
First, the principle of the heating furnace 1.Purpose The purpose of the heating is to heat the billet to a uniform, suitable rolling temperature (austenitic structure). After the temperature is raised, the first is to improve the plasticity of the steel, reduce the deformation resistance, and make the steel easy to deform. For example, the…
Analysis of five common failures in steel rolling Card steel Card steel refers to a fault phenomenon in which the rolling stock is stuck on the rolling line due to the influence of the surrounding environment during normal operation, and cannot be rolled in the downstream direction. The main reasons for this are: the size…
