浇注料、可塑料、喷涂料怎么选｜Castable, Plastic or Gunning Mix: Choosing the Form

摘要：不定形耐材三种主要形态，比的不只是材料价，更是施工方式与停窑窗口的匹配。按部位几何、工期、班组技能三个维度给出选择顺序。
Abstract: Three monolithic forms differ less in material price than in how they match geometry, downtime and crew skill. A selection order by geometry, schedule and the crew you actually have.

正文： 同一个窑体检修，浇注料、可塑料、喷涂料三种方案报出来，材料价能差一倍，但真正决定总成本的是施工方式跟停窑窗口、部位几何的匹配度。
Main text: Three monolithic options for the same overhaul can differ twofold on material price, yet total cost is decided by how the placement method matches the shutdown window and the geometry.

一、几何决定形态
1. Geometry picks the form

大面积平直墙面与炉底，浇注料支模整体浇注最密实；不规则部位、炉墙热修补，可塑料捣打随打随用；高空与难支模的部位，喷涂料免模施工是唯一解。先看部位再选料，顺序不能反。
Large flat walls and hearths take castable, formed and vibrated for density; irregular spots and hot wall repairs take plastic rammed in place; overhead and unformable sections are gunning-only territory. Look at the location first, then the material.

二、停窑窗口定工法
2. The shutdown window sets the method

• 浇注料要养护加烘烤，适合计划性大修。
  Castable needs curing plus baking — for planned overhauls.
• 可塑料免模免烘烤，抢修窗口几十小时的用它。
  Plastic needs no forms or bake — for short emergency windows.
• 喷涂料效率最高，但回弹和密度决定了它更适合修补而非新建。
  Gunning is fastest, but rebound and density suit repair better than new build.

三、班组技能别高估
3. Do not overrate the crew

浇注料振捣不透等于白做，可塑料捣打力度不够留空洞，喷涂手法差回弹翻倍。评估自家班组真实技能水平再定方案，必要时请厂家驻场带第一个工班，这笔钱比返工便宜。
Under-vibrated castable is wasted work; weak ramming leaves voids; poor gunning doubles rebound. Size the plan to the crew you truly have, and if needed pay the supplier to lead the first shift — cheaper than redoing it.
