  • Continuous casting unmanned ladle casting system

  • Steel position disassembly cylinder manipulator

Two ABB manipulators, model IRBA67, are installed on the ladle steel side.The system mainly includes: identifying and positioning equipment;Disassembly and installation of slide oil cylinder jig;Medium pipe plugging fixture;Air control box and its pipelines;Robot pipeline package, etc.These two manipulators are mainly used to realize the functions of oil cylinder, energy medium pipeline and electric pipeline automatic plugging and drawing.


  • Casting steel position installation and disassembly of long nozzle main manipulator

Two KUKA manipulators, model KRF51, are installed on the ladle steel side. The system mainly includes: the identification and positioning equipment of the downhole; Oil cylinder jig; Bonner laser sensor; The probe box; Probe removal device; Probe removal device; Temperature measuring gun; Sampling gun; Test gun storage rack; Long nozzle for storage of fixing frame; Long nozzle movable fixture; Change the long nozzle clamp; Long nozzle bowl cleaning device; Sealing ring blanking mechanism; Ladle oxygen-burning gun; Oxygen gun clamping tool; Disassembly and installation of slide oil cylinder jig; Oxygen gun treatment equipment and other components. These two manipulators and their systems are mainly responsible for the replacement and cleaning of the long nozzle, the addition of sealing rings, eye burning, drainage, the addition of covering agent and temperature measurement and sampling.


  • Casting steel position auxiliary sorting overlay manipulator

Two ABB manipulators, model IRBA67, are installed on the ladle steel side.The system mainly includes: material bag identification and positioning equipment;Covering agent fixture;Bin;Hopper;Hopper placement rack, etc.These two manipulator systems mainly complete the sorting of covering agent


  • Bulk slag detection system

The slag detection system of ladle is mainly based on the installation of electromagnetic induction coil on the inlet of large ladle, and the purity of molten steel is judged by the principle of current signal change caused by electromagnetic induction when molten steel flows through.Thus whether to judge whether the outflow of steel slag or not.If the lower slag exceeds the set value, the system automatically closes the ladle slide oil cylinder and finishes pouring steel to ensure the purity of the molten steel flowing into the middle ladle.Now the ladle modification has been completed, the wiring has been completed, and the cold test of the project has been completed.


  • Intermediate level system

The liquid level control system of the ladle is mainly used to measure the weight of molten steel in the ladle by weighing the ladle, so as to judge the liquid level of molten steel in the ladle.If the liquid level is too high, the opening of the ladle inlet should be adjusted appropriately to reduce the flow rate of ladle; on the contrary, the flow rate of Ladle ladle should be increased to control the liquid level of ladle


  •  Automatic crystal level control system

The automatic control system of liquid level of crystallizer is mainly to install cesium source detection unit inside the crystallizer, and then according to the liquid level of the crystallizer, the detection unit generates 4-20mA signals corresponding to the height of the liquid level. If the liquid level is high, the drawing speed will be gradually increased, otherwise, the drawing speed will be reduced to achieve the purpose of controlling the balance of the liquid level.The crystallizer level automatic control system can greatly reduce the working strength of workers, and to a large extent avoid the steel leakage accident caused by personnel’s operation mistakes


  • Automatic slag adding system

The automatic slag adding system USES the principle of gas conveying to transport the mold protective slag in the hopper through the pipeline to the mold.The system consists of hopper assembly, protective slag conveying line, slag nozzle and bracket, electric control box, air control box, etc.The hopper is installed on the operation platform of the big bag, and the protective slag falls into the hopper. The slag quantity is controlled accurately by PLC. The protective slag, which is accurately measured, passes through the protective slag conveying pipeline and slag nozzle assembly.The use of automatic slag adding greatly reduces the operation intensity of workers and improves the automation level of equipment.[/vc_column_text][/vc_column][/vc_row][vc_row btn_title=”Improve the ladle lining life” btn_link=”” btn_align=”ubtn-center” btn_size=”ubtn-large” btn_width=”” btn_height=”” btn_padding_left=”” btn_padding_top=”” btn_title_color=”#ffffff” btn_bg_color=”#6b96bf” ult_btn_custom_onclick=”” btn_hover=”ubtn-no-hover-bg” btn_anim_effect=”none” btn_bg_color_hover=”” btn_title_color_hover=”” button_bg_img=”” btn_icon_pos=”ubtn-sep-icon-at-left” btn_border_style=”” btn_color_border=”” btn_color_border_hover=”” btn_border_size=”1″ btn_radius=”3″ btn_shadow=”” btn_shadow_color=”” btn_shadow_color_hover=”” btn_shadow_size=”5″ btn_shadow_click=”” enable_tooltip=”” tooltip_text=”” tooltip_pos=”left” btn_font_style=”font-weight:bold;” btn_font_size=”desktop:20px;” rel_attr=”” ult_btn_custom_onclick_code=”” css_adv_btn=”” btn_font_family=”” btn_line_height=””][vc_column][ult_buttons btn_title=”LMM GROUP One stop solution for steel industry – Steel Intelligent leader.” btn_align=”ubtn-center” btn_title_color=”#ffffff” btn_bg_color=”#6b96bf” icon_size=”32″ btn_icon_pos=”ubtn-sep-icon-at-left” btn_font_style=”font-weight:bold;” btn_font_size=”desktop:15px;”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]
