I noticed there aren't many steel recipes,
so I tried using a recipe disabled by the "248k redux mod" and made it more realistic.
I'd be happy if you implemented it in the modpack.

-- steel blend recipe
local r_blend = data.raw.recipe["fi_materials_industrial_steel_blend_recipe"]
if r_blend then
r_blend.ingredients = {
{type="item", name="atom-coal-dust", amount=4},
{type="item", name="5d-iron-dust", amount=10},
{type="item", name="atom-aluminum-dust", amount=2},
{type="item", name="atom-manganese-dust", amount=3}
}
r_blend.energy_required = 8
end

-- steel recipe
local r_steel = data.raw.recipe["fi_materials_steel_recipe"]
if r_steel then
r_steel.ingredients = {
{type="item", name="fi_industrial_steel_blend_item", amount=1},
{type="item", name="kr-silicon", amount=1}
}
r_steel.energy_required = 15
r_steel.result = nil
r_steel.results = {
{type="item", name="steel-plate", amount=4}
}
end

-- tech
local r_tech = data.raw.technology["fi_crusher_tech"]
if r_tech then
r_tech.effects = r_tech.effects or {}

table.insert(r_tech.effects, {
    type="unlock-recipe",
    recipe="fi_materials_industrial_steel_blend_recipe"
})

table.insert(r_tech.effects, {
    type="unlock-recipe",
    recipe="fi_materials_steel_recipe"
})

end
