class=\"wp-block-heading\">Slag pot handling, slow cooling and slag dumping in the cooling area<\/h3>\n\n\n\n<p>In the slag slow cooling yard, the metallurgical gantry crane handles slag pots, including hot molten slag pots (such as side-blown furnace molten slag at about 1250 \u00b0C), slow-cooling pot transfer and pot tilting to dump solid slag.<\/p>\n\n\n\n<p>The slow cooling process involves intense heat, a small amount of SO2 gas and dust, water spray mist, and occasionally <a href=\"https:\/\/en.wikipedia.org\/wiki\/Slag\" target=\"_blank\" rel=\"noopener\">slag<\/a> splashing and high-temperature melt spillage (contact temperature up to 800 \u00b0C).<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-1

ladles from the preheating area to the furnace area and between casting areas to support metallurgical operations.<\/p>\n\n\n\n<p>This work takes place in a high-temperature workshop, where the ladle and adjacent structures are exposed to heat radiation from molten metal; the pouring area may also produce fume, particulate matter and emissions from the thermal decomposition of mould binders.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"952\" height=\"952\"

Features of the MGY Gantry Crane<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Thermal insulation reduces the effect of heat radiation<\/h3>\n\n\n\n<p>Key structural members such as the main girder and legs are provided with thermal insulation to withstand high-temperature radiation and to ensure stable long-term operation in a high-temperature workshop.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Dust and corrosion protection configured for the project<\/h3>\n\n\n\n<p>The electrical enclosure protection, component sealing, and steel structure corrosion protection solutions for MGY gantry cranes can be configured with rust-resistant and corrosion-resistant components, dustproof design, and surface protection measures according to specific conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Speed regulation reduces starting and stopping shocks under heavy load<\/h3>\n\n\n\n<p>The hoisting mechanism uses stator voltage regulation for speed control and the travelling mechanism uses variable frequency drive, so starting and braking are smooth and the lifted load can be positioned accurately.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Centralized control with PLC, HMI and master controller<\/h3>\n\n\n\n<p>The WLK-type master controller issues operating commands such as hoisting, lowering and travelling; the PLC receives the commands and controls the corresponding mechanisms, and the HMI touch screen provides centralized display and operation of the control system. The master controller has clear gear positions and a zero-position self-return and locking function, which helps the operator select the travel direction and speed step and reduces the risk of the handle not returning to zero or being operated by mistake.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Finite element analysis verifies structural strength and deformation<\/h3>\n\n\n\n<p>Finite element analysis is used to optimize the load distribution of the main load-bearing structural members, which gives excellent rigidity and resistance to deformation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Standards and Specifications: Why Choose KSCRANE<\/h2>\n\n\n\n<p><a href=\"https:\/\/std.samr.gov.cn\/hb\/search\/stdHBDetailed?id=8B1827F169F0BB19E05397BE0A0AB44A\" data-type=\"link\" data-id=\"https:\/\/std.samr.gov.cn\/hb\/search\/stdHBDetailed?id=8B1827F169F0BB19E05397BE0A0AB44A\" target=\"_blank\" rel=\"noopener\">JB\/T 7688.1<\/a> Metallurgical cranes: Technical requirements, Part 1: General requirements is the Chinese industry standard for metallurgical cranes. As a well-known Chinese crane manufacturer, KUANGSHAN CRANE took part in formulating this industry standard and applies its requirements to the design, manufacture and inspection of KUANGSHAN CRANE products, including the MGY gantry crane. For a buyer, this means product quality has clear technical indicators and test results that can be verified, so selection and acceptance are better founded.<\/p>\n\n\n\n<p>The MGY gantry crane meets the following standard requirements:<\/p>\n\n\n\n<ul>\n<li>Motor insulation: when the ambient temperature exceeds 40 \u00b0C, motors with class H insulation are selected, or other necessary measures are taken.<\/li>\n\n\n\n<li>Static load test: 1.25 times the rated working load; after the test the main load-bearing members shall have no cracks, permanent deformation or other specified defects.<\/li>\n\n\n\n<li>Dynamic load test: 1.1 times the rated working load; operation is normal and the brakes and safety devices act reliably.<\/li>\n\n\n\n<li>Main girder camber: with the trolley at the end of the span, the actual camber of the main girder is not less than 0.7S\/1000, where S is the span.<\/li>\n\n\n\n<li>Hoisting speed and braking: when the rated speed of a hook-type hoisting mechanism exceeds 5 m\/min, electrical braking shall be used to reduce the speed so that, before braking with the rated load lowered, the motor speed falls below one third of the synchronous speed.<\/li>\n\n\n\n<li>Lowering limit: where a lower limit position is required, a lowering limiter shall be provided; at least 2 turns of wire rope shall remain on the drum, not counting the fixed turns.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Information Required for a Quotation<\/h2>\n\n\n\n<p>To determine the equipment dimensions, spreader and mechanism configuration accurately, please provide:<\/p>\n\n\n\n<ul>\n<li>Pot parameters: empty and loaded mass, overall dimensions, lifting lug dimensions and centre distance, internal medium and maximum temperature;<\/li>\n\n\n\n<li>Crane parameters: span, lifting height, rail length and working frequency;<\/li>\n\n\n\n<li>Site conditions: indoor or outdoor installation, ambient temperature, wind speed, dust and corrosion conditions;<\/li>\n\n\n\n<li>Operating requirements: pot transfer route, vehicle dimensions, control method and necessary safety interlock requirements.<\/li>\n<\/ul>\n\n\n\n<p>This information is used to determine the lifting capacity and spreader, the equipment dimensions and duty class, the environmental protection, and the operating and safety interlock configuration.<\/p>","protected":false},"excerpt":{"rendered":"The MGY gantry crane is one of the most widely used types of lifting machinery.
