According to the current conventional plan to upgrade the G6 thermal field from G5, the entire thermal field needs to be replaced, so that the inner space of the thermal field meets the requirement of the G6 crucible size of 1040mm. However, due to the enlarged inner space of the heat insulation cage, the entire original G5 thermal field insulation parts cannot Fits large insulated cage sizes

Embodiment Construction
[0025] A kind of method that G5 polycrystalline ingot furnace is transformed into G6 polycrystalline ingot furnace, such as figure 1 , figure 2 , image 3 shown, including steps:
[0026] 1) The external insulation board 3 of the heat insulation cage is grooved on the outside, and the groove depth is 30mm. The external insulation board 3 of the heat insulation cage is provided with 4 pieces, which are divided into 2 pieces on the upper layer, 2 pieces on the lower layer, and 2 pieces of heat insulation cage external insulation boards on the upper layer The slot size on 3 is 490×50×30mm in length*width*height, the number of slots on 3 is 3 on the left and 2 on the right, and 2 insulation panels on the lower layer The size of the slots on the outer insulation board 3 of the cage is 658×50×30mm in length*width*height, and the number of slots on the outer insulation board 3 of the lower two insulation cages is 3 on the left and 2 on the right;
[0027] 2) There are 4 pieces of...

A method for modifying a G5 polycrystal ingot furnace into a G6 polycrstal ingot furnace comprises the steps that a groove is formed in the outer side of a heat insulation board outside a heat isolation cage, the depth of the groove is 30 mm, chamfering 45-degree cutting treatment is performed on the left side of the heat insulation board inside the heat isolation cage, a corner heat isolation board is arranged at the corner of the heat isolation cage, two upper heat insulation boards are arranged inside the heat isolation cage, an upper fire blocking strip and a lower fire blocking strip are arranged at the bottom of the heat isolation cage, a DS block is widened, a widening strip is arranged on the DS block, and an original G5 lower heat isolation base plate is adopted as a modified upper heat isolation base plate; a graphite electrode is arranged on a side face heater suspension arm; grooves are formed in the joints of an A1 face side face heater, an A4 face side face heater, an A3 face side face heater and the side face heater suspension arm. On the condition that the steel heat isolation cage is not changed, original G5 is modified, and therefore the overall heat zone can meet the requirement of the G6 ingot casting internal space size; due to the fact that a heat isolation board fitting can be reutilized in structural design, the method has the advantages that the G6 updating modification cost is low, and installation is convenient.
Description
technical field [0001] The invention relates to a method for transforming a G5 polycrystalline ingot furnace into a G6 polycrystalline ingot furnace. Background technique [0002] At present, with the increase of domestic installed capacity, the production of silicon wafers has expanded. For large ingot manufacturers, the overall upgrade of the original G5 furnace base to the G6 thermal field requires a large amount of funds, which cannot meet the requirements at present. How to use the current G5 It is imminent to carry out G6 thermal field upgrade technology under thermal field conditions. [0003] Taking the current GT450 furnace base as an example, the inner space of the heat insulation cage is 1350×1350×1245mm, the size of the top insulation board is 1170×1170×90mm, and the inner insulation size of the heat insulation board is 1214×1149×45mm. The size is 1255×1149×45mm. According to the current conventional plan to upgrade the G6 thermal field from G5, the entire ther...
