Welding cinder ladle processing technology provided by the present invention is as follows:

Whole cinder ladle makes, and board selection low-alloy high-strength plate Q345 makes, according to user environment temperature, sheet material Material from Q345B to Q345E, carry out corresponding selection respectively, the blanking respectively of each parts makes, and first trunnion base assembly 1 is first carried out Welding and assembling, weld after then positioning with Cylinder assembly, and cylinder 2 (can be used 1～3 pitch circles by forcing press is compressing Frustum docks, and every section of frustum of a cone uses 2～6 sections of compactings to form), gusset etc. uses CNC cutting, at the bottom of flat bag (see accompanying drawing 20, 21) using low-alloy high-strength plate to prepare, finished product directly carries out welding with cylinder 2.Adopt (see accompanying drawing 5,12) at the bottom of spherical bag Make by two kinds of methods: a kind of method is hot-forming, then (owing to spherical bag Bottom Shape is simple, select bag with barrel soldering More end internal diameter 1000mm～1300mm, have mould to use, manufacturing cost be greatly reduced).Wherein barrel designs according to load, The difference of volume, selects 60-100mm low-alloy high-strength plate to make；When using hot press forming technology to make at the bottom of spherical bag, permissible It is fabricated to uniform thickness, it is ensured that wrap the support strength at the end and save material by wrapping each portion, the end.Another kind is fine casting, uses and cylinder The material that performance parameter is close, is optimized design by the bottom of bag, alleviates the weight at the bag end to greatest extent；Bag end weight only accounts for always About the 10% of weight.When using casting method to make at the bottom of spherical bag, owing to belonging to welding dissimilar materials, weld seam bears load simultaneously Lotus, weldquality be related to produce whether can safe operation, therefore to guarantee to wrap the reliable of the end and cylinder weld seam, it is necessary to from bag The many-sides such as basal cross section, the structure of the bag end and cylinder docking site coordination portion, overall construction design consider.Consider To the bearing capacity at the bag end, being fabricated to variable cross-section the bag end, the bag end, is consistent with cylinder with the thickness of cylinder joint, from the bag end Upper edge hole is to bag end lowest part thickness progressive additive, and thickness is from 60-150mm.At the bottom of spherical bag with the butt weld of cylinder outside, Arranging horizontal ring flat-plate 3 (see accompanying drawing 5), horizontal ring flat-plate 3, according to the difference of cinder ladle volume, takes different-thickness and ring flat-plate width, water Flat ring plate 3 thickness 40-300mm, horizontal ring flat-plate 3 width (diametric(al)) is 100-300mm, and ball is held on the inclined-plane of horizontal ring flat-plate 3 At the bottom of shape bag, sharing the load of bag end butt weld, the most horizontal ring flat-plate about 3 has the thickness 40-80mm of circumference uniform distribution 6-12 bar Longitudinal gusset 5 (see accompanying drawing 1) composition network structure, the load of bag end butt weld is shared by longitudinal gusset, acts on In cylinder, strengthen the structural strength at the bag end and cylinder position, with the vertical load of copper ashes in the butt weld shared bag at the bag end Lotus (exposing at cylinder butt weld when the bag end, such as structure shown in Figure 31, can open through butt weld by all longitudinal gussets If fabrication hole, avoiding butt weld, the bag end, is shared by longitudinal gusset with the stress of cylinder butt weld), at the bottom of spherical bag and cylinder Welding seam design be one side V-butt, bevel angle 30-50 °, b is 3-10mm；Through Strength co-mputation, and consider at the bottom of spherical bag The construction features
